Could the problems of this thread be augmented by our own deteriorating vision?
I think it may well be. Probably since age about 40-ish every time I had eyes tested I've moaned a about night-driving, and always been told 'your over 40, what do you expect'?
Even so, car and accessory makers and need to understand that over 40s drive too, and the characteristics of their eyesight must be catered for and taken into account.
I'm actually quite a lot over 40 these days; extremely so, in fact. But pretty sure that's about when I started moaning about night driving. Thankfully, eyes still healthy though, just normal ageing I am assured....
